Probing the out‐of‐equilibrium dynamics of driven colloids by X‐ray photon correlation spectroscopy
Journal of Applied Crystallography, Volume 58, Issue 2, Page 535-542, April 2025.This article presents an application of X‐ray photon correlation spectroscopy (XPCS) to probe the out‐of‐equilibrium dynamics in a driven colloidal system. XPCS enables the investigation of direction‐dependent non‐equilibrium dynamics and the gradual return of the suspension to equilibrium Brownian behaviour.

, 2017 Congruence lattices of semiprime algebras from semi--degenerate congruence--modular varieties fulfill the equivalences from B. A. Davey`s well--known characterization theorem for $m$--Stone bounded distributive lattices, moreover, changing the ...

Multiphysics Simulation Methods in Computer Graphics
Computer Graphics Forum, EarlyView.Abstract Physics simulation is a cornerstone of many computer graphics applications, ranging from video games and virtual reality to visual effects and computational design. The number of techniques for physically‐based modeling and animation has thus skyrocketed over the past few decades, facilitating the simulation of a wide variety of materials and ...

Multiplicative order convergence in $f$-algebras
, 2019 A net $(x_\alpha)$ in an $f$-algebra $E$ is said to be multiplicative order convergent to $x\in E$ if $\x_\alpha-x\u\oc 0$ for all $u\in E_+$. In this paper, we introduce the notions $mo$-convergence, $mo$-Cauchy, $mo$-complete, $mo$-continuous and $mo ...

A General Method for Resampling Autocorrelated Spatial Data
Geographical Analysis, Volume 57, Issue 2, Page 302-319, April 2025.Abstract Comparing spatial data sets is a ubiquitous task in data analysis, however the presence of spatial autocorrelation means that standard estimates of variance will be wrong and tend to over‐estimate the statistical significance of correlations and other observations. While there are a number of existing approaches to this problem, none are ideal,

Spatial and spatiotemporal volatility models: A review
Journal of Economic Surveys, EarlyView.Abstract Spatial and spatiotemporal volatility models are a class of models designed to capture spatial dependence in the volatility of spatial and spatiotemporal data. Spatial dependence in the volatility may arise due to spatial spillovers among locations; that is, in the case of positive spatial dependence, if two locations are in close proximity ...

Variable sets over an algebra of lifetimes: a contribution of lattice theory to the study of computational topology [PDF]
, 2015 A topos theoretic generalisation of the category of sets allows for modelling spaces which vary according to time intervals. Persistent homology, or more generally, persistence is a central tool in topological data analysis, which examines the structure ...

On principal congruences in distributive lattices with a commutative monoidal operation and an implication [PDF]
, 2018 In this paper we introduce and study a variety of algebras that properly includes integral distributive commutative residuated lattices and weak Heyting algebras. Our main goal is to give a characterization of the principal congruences in this variety. We apply this description in order to study compatible functions.

The Picard group in equivariant homotopy theory via stable module categories
Journal of Topology, Volume 18, Issue 2, June 2025.Abstract We develop a mechanism of “isotropy separation for compact objects” that explicitly describes an invertible G$G$‐spectrum through its collection of geometric fixed points and gluing data located in certain variants of the stable module category.

Lattice of closure endomorphisms of a Hilbert algebra
, 2017 A closure endomorphism of a Hilbert algebra A is a mapping that is simultaneously an endomorphism of and a closure operator on A. It is known that the set CE of all closure endomorphisms of A is a distributive lattice where the meet of two elements is ...
